Krypton-85 (85Kr36) was released at Three Mile Island.
It is estimated that the amount of radioactive gases released from the Three Mile Island Unit II incident in 1979 was less than 481 PBq (13 million curies) and that the amount of Iodine-131 released was less than 740 GBq (20 curies).
Three mile island was the site of the worst nuclear 'accident' in america's history. The reactor went into meltdown - releasing radioactive material into the atmosphere.
Three Mile Island related to an incident which occurred in Dauphin County, Pennsylvania on March 28th, 1979. On this Wednesday morning, around the time of 4am, there was a partial nuclear meltdown which released radioactive gases and radioactive iodine into the environment.
Any nuclear accident such as 3 Mile Island can contaminate nearby forests. Radioactive strontium is released during nuclear decay, which can be taken up by plants, since it mimics calcium. This can later be ingested by people, making them sick.
After the crisis was over this reactor was inspected and found to have undergone a very significant but partial meltdown. It was considered to be unrepairable and has sat idle since then, some cleanup was done and the material removed was disposed of as appropriate for radioactive hazardous material. The other undamaged reactors on the site continue to operate.

All the three elements are generally non-radioactive.
It's essentially impossible to answer the question, as the answer depends on the size, nature, and specific location of the explosion.It's probably important to clear up a misconception here. Nuclear power plants do not explode like nuclear bombs. They simply cannot do so. There can be explosions at a nuclear plant, but these are chemical explosions like you could potentially get at any factory.The problem with an explosion at a nuclear plant is that, even though it's caused by a chemical reaction and not a nuclear one, it tends to spread radioactive material around.The worst case scenario is that radioactive material would be released into the area around the reactor... again, how large an area depends on how big the explosion is, and how bad this would be depends on part in what precise radioactives were released. For example, while the Three Mile Island accident released a considerable amount of radioactive material, several scientific studies have concluded that there were no measurable adverse health effects and that the average person within a ten-mile radius of the plant got about the equivalent radiation dose of one extra chest x-ray that year. Certain elements are more dangerous than others because of their role in the body's biochemistry... radioactive iodine and strontium, for example, are dangerous because the body concentrates them (in the case of iodine) or incorporates them into bone structure (in the case of strontium).
